the wand — write in the air, type into anything
Co-founded Input-A (Inputa Inc., Delaware) to build the wand: a handheld that types what you write in the air. A compact neural net reads handwriting from a few-dollar motion sensor — recognition runs on the device in 25–28 ms on Nordic's nRF54LM20B, no camera, no microphone, no cloud — and it connects to TVs, phones and computers as a standard Bluetooth keyboard. Twenty years of small-silicon audio ML, pointed at motion instead of sound. Measured the honest way: 400+ paid study participants across 23 studies, scored on writers the model has never seen. Five provisional patent families filed. TVs today; the glasses era is the point.
